#
# Where:
#	srcdir: is the directory where the testfile is
#	cmd:	is the command to be executed.

# This function executes a passed in command and then determines the chksum 
# of the resulting file.  The chksum components are checked against the ones
# passed in to determine if they are equal.  If they are equal, 0 is returned
# otherwise 1 is returned.
#
# Usage:
# migrate destdir oldsuma oldsumb command_to_execute
#
# Return value: 0 on success
#		1 on failure
#
# Where:
#	destdir: is the directory where the command is to be executed on
#	oldsuma: is the first part of the values returned by sum
#	oldsumb: is the second part of the values returned by sum
#	cmd: is the command to be executed;
#		E.g.
#		"$TAR xf $TESTDIR/tar${TESTCASE_ID}.tar"
